Kelly Computer Stores has a network configured based on the schema below. Each location consists of one LAN and are serially connected over WAN links. All routers are completely configured and in full working order with the exception of the routing protocol on the 198.150.13.0/24 and 223.11.34.0/27 networks on the Galway router. Please configure the routing protocols on the Galway router interfaces.
The routers have been configured with the following specifications:
The routers are named Gawlay, Limerick and Dundalk.
OSPF is the routing protocol within a single area.
The clocking is provided on the Serial 0 interfaces.
The secret password on all routers is "cisco".
Tips: Use Host B to connect to the Galway router. Toggle F11 to access/exit fullscreen mode.
Successful Lab Completion
You will not be told this on the actual exam but you have successfully completed the Lab.
Good job!

Configure OSPF routing protocol?
Think "classless" -- what class are we working on + last octet?
Class C address -- network portion: - first 3 octets + fourth octet + wildcard + area 0.
S Host Range Broadcast
.0
.32
.64
.96 .97 - .126 .127
.128
-->
.97 falls within the .96 subnet (fourth octet) -- so we can use it.
Subnet: 223.11.34.96 - Wildcard: 0.0.0.31 - area 0
Write down router ospf statements for the two networks directly attached to the Galway router:
router ospf 100 - (100 is the Process ID number- it may or not be given - for the exam - pick a number of your choice.)
network 198.150.13.0 0.0.0.255 area 0
network 223.11.34.96 0.0.0.31 area 0
Remember -- Class C network addresses (classless): Network portion = first 3 Octets + fourth octet + wildcard + area 0.
Now input the statements into the CLI. Note: I started with "show running-config" to verify the subnet masks on the interfaces. You don't have to do this.
No matter what -- if you go over 15 minutes on an actual exam Lab - get to the "Privilege EXEC mode" prompt and input "copy run start".
Special note: The wildcard logic is exactly the same as that used for ACL statements.
